Method for advancing products arranged consecutively in at least one row which are moved forwards into a packaging machine

A method for advancing products arranged consecutively in at least one row which are moved forwards into a packaging machine to be wrapped in at least one stretch film comprising the following steps:

• ordering and advancing said products arranged consecutively in the at least one continuous row;
• wrapping said products arranged consecutively in the at least one continuous row in said at least one stretch film;
• evacuating said products arranged consecutively in the at least one continuous row and wrapped in said at least one stretch film;
• wherein in at least one of said steps, guides with reduced friction are used for guiding and/or supporting said products arranged consecutively in the at least one continuous row and/or wrapped in said at least one stretch film;
• wherein acoustic generation systems comprise the guides with reduced friction for guiding and/or supporting said products, which are configured to generate a surface vibration of said guides capable of reducing contact friction with the guides with respect to said products wrapped in said at least one stretch film.
